[0002] At present, CNC milling machines are a kind of automatic processing equipment developed on ordinary milling machines. There are two types of CNC milling machines: without tool magazine and with tool magazine. The CNC milling machines with tool magazine are called machining centers, but most of the current CNC milling machines are only equipped with one set of milling cutters, which is not convenient for disassembly and installation of the milling cutters, resulting in insufficient convenience in use.

[0003] The prior art CN213969174U provides a CNC milling machine that is easy to replace blades. When the milling cutter needs to be replaced, the staff screws the bolts on the outside of the clamping block one and the clamping block two. At this time, the staff pulls out the milling cutter inside the clamping block one and the clamping block two. At this time, the staff can insert the fixed plate and the limit block into the inside of the installation groove one, and the installation groove one can be used to limit the limit block and the fixed plate. At this time, the staff screws the bolts in the opposite direction until the milling cutter is fully engaged with the clamping block one and the clamping block two, and the installation is completed. The installation groove one and the fixed plate can be used to limit the milling cutter, which effectively prevents the milling cutter from detaching. The operation is simple and the design is reasonable.

[0004] However, in the prior art, there is no protective measure when replacing the milling cutter, which makes it easy for accidental touch and machine tool failure to cause the drill bit to rotate, thereby injuring the user, making the device insufficiently protective when replacing the milling cutter.
